Fics like MHA A Spartan Returns

Due to a mad scientist testing the limits of a dimensional portal quirk. The GateKeeper somehow came into possession of one of the various variants of Izuku. Apparently, the boy was kidnapped off the streets and used as a test subject for that mad scientist. Now with a spare Izuku and no way to send him back anytime soon. He decides to make a deal with the kid and send him to the universe to replace John 117, who died before even being placed in the Spartan program. 43 years later, after Izuku 117, also known as The Master Chief, had destroyed The Didact ship, The GateKeeper returns and gives him a new deal. In exchange for saving Cortana's life, he would head back to his universe and prep for the coming threats that will eventually come to his world. Luckily for him, he wasn't going alone since Blue team decided to tag along.
